I'm considering a set of these in hyper silver for a 135i. What do people think about 18s versus 19s? I don't wanna destroy the ride quality and I'll be swapping out of run flat tyres. From people's experiences how does the ride quality with 18s and run flats compare to 19s without run flats?

Fitment is spot on for the 18s F&R. I didn't have any rubbing at all on our recent cruise, with some aggressive cornering and even mid bump corners didn't cause any rubbing. I'm not lowered unlike Rey's coils.

I don't think Jason has 19s in our offset. You may have to go VMR or Alufelgens from USA.
